RS-485, also known as TIA-485(-A) or EIA-485, is a standard defining the electrical characteristics of drivers and receivers for use in serial communications systems. Electrical signaling is balanced, and multipoint systems are supported. The standard is jointly published by the Telecommunications Industry Association and Electronic Industries Alliance (TIA/EIA). Digital communications networks implementing the standard can be used effectively over long distanc… WebApr 12, 2024 · uart串口怎么跟rs232对接_rs232和rs485的区别一、UART通信UART是Universal ... 二进制形式表示就是0b11100100，在UART通信过程中，是低位先发，高位后发的原则，那么就让TXD首先拉低电平，持续一段时间，发送一位0，然后继续拉低，再持续一段时间，又发送 ...
